Leading industry wheel dynamics expert and ceo of edco wheels paul lew backs this up and reckons it makes ceramic bearings a poor choice for hubs and headsets also adding that they offer no weight savings and are only beneficial in environments where high rpm revolutions per minute are required.

Additionally silicon nitride does not deform under load keeping contact points with the bearing races to a minimum. Because ceramic races are more brittle than steel. Full ceramic wheel bearings would be an amazing way to reduce friction in hubs.
